SPECIFICATION forming part of Letters Patent No. 617,125, dated January3, 1899.

Application filed May 17, 1897. Serial No. 636,961. (No model.)

To @ZZ whom. if may concern:

Be it known that LCARL OscAR RosKorEN, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Bottle-Stoppers,of whichthe following is a specification.

My invention pertains fo bottlestoppers, the construction and advantagesof which will be hereinafter set forth, reference being had to theannexed drawings, in which- Figure l is a vertical sectional vieT of myimproved stopper and so much of a bottle as is necessary toproperlyillustrate the device, the parts being in such relation that theliquid can readily flow out; Fig. 2, a similar view showing the parts inthe reverse relation; Fig. 3, a perspective view of the clamping-springdesigned to hold the parts together and to maintain them in thebottleneck; Figs. 4., 5, and 6, cross-sectional views of Fig. 2 on thelines l l, 2 2, and 3 3, respectively; Fig. 7, a perspective view of asection of the stopper; Figs. 8, 9, and 10, vertical sectional views ofmodified forms of the device; and Figs. 1l, 12, and 13, cross-sectionalviews on the lines 4. 4., 5 5, and 6 6 of Figs. 8, 9, and l0,respectively.

The object of my invention is to provide a cheap and efficient stopper,one which may be readily inserted into the neck of the bottle after itis filled, permitting free egress of the contained liquid when desired,but preventing the refilling of the bottle.

The body of the stopper is formed of two parts A A, the parts beingduplicates of each other. In the form shown they are semicircular ingeneral outline, and when placed together form a circular body whichwill approximately close the neck B of the bottle when placed therein.The sections may be made of any desired material, and one die will ofcourse do for the making of both sides, as the parts are duplicates. Inthe fiat face of each section there is formed a series of deepdepressions C, connected by smaller and shallower depressions, whichwhen the two sections are in place form large pockets D, connected bysmall or restricted openings a. The openings o; are of course formed atthe upper and lower ends of the Stoppers. Any

number of pockets may be formed, as desired, according to the length ofthe neck of the bottle in which the stopperis to be used. In Figs. l and2 four pockets are shown, being designated by the letters D, D', D2, andD3. In the pockets D' and D3 there is placed a ball E, the specificgravity of which is greater than that of the liquid which is placed inthe bottle, while in the pockets D and D2 are placed balls F, theirspecific gravity being lighter than that of the contained liquid.

The ends of the pockets D and D2 are curved to form a bearing againstwhich the balls may seat, and the interior diameter' of said pocketsnear each end is also approximately the same as that of the ball. At thecentral portion of all of the pockets there is formed a polygonalrecess, preferably square, as denoted by G, Figs. l and 2 ands to 7,inelusive.

Extending out intothe pockets D and D3 at that end near the dischargeend and just above the polygonal recess are prongs or studs H, whichprevent the specifically heavy balls E from closing the openings a whenthe bottle is inverted to discharge the contents. This relation is shownin Fig. l, the specifically light balls F floating on the liquid andoccupying a position in the polygonal recess G, thereby permitting theliquid to iiow freely therearound.

In Fig. 8 but three pockets are shown, and instead of making therecesses Gr angular they are made cylindrical, though the angularformation is preferred. In said figure.

and in Figs. 9 and l0 the lower end of the stopper is formed with arecess in which is seated a packing-ring I, of cork or the like, toform, if necessary, a tight joint with the bottle-neck,due to anyimperfections therein.

Under some conditions, and particularly where but one specifically lightball is used (Wood or cork or like easily-punctured material) and itoccupies the upper pockets, as in Figs. 9 and 10, it may be desirable tointerpose some obstruction to the passage of wire or the like into thedischarge-opening. To this end, as illustrated in said figures, thesections A A are formed near the discharge ends with recesses J, withinwhich, when the parts are assembled, is mounted a disk K,

IOO

provided with openings L, which are to one side of the center and out ofline with the opening a.

To secure the sections A together and to securely hold them within theneck of the bottle, I employ a spring-collar M. (Shown in Fig. Thespring is circular in form and split down one side, as shown. Itsoutside diameter is just equal to that of the interior diameter of theneck of the bottle, and recesses or seats are formed upon the exteriorface of the sections A, in which it is seated when the parts areassembled and ready to be put in place.

Spring-fingers N are formed integral with the body of the spring andengage recesses O formed in the interior of the bottle-neck. When theparts are shoved down into the neck and the spring-fingers once engagethe recesses, it will be seen that it is impossible to withdraw thestopper as a whole or one of the sections A thereof.

The balls E and F of course act as valves, and while with theconstruction set forth they permit the free egress of the liquid theystill prevent the bottle being reiilled, as indicated in Fig. 2. So,too, they do away with the necessity of any other seal or cork for thebottle, though a cork or other sealing device may be employed inconnection with the stopper.

Having thus described my invention, what I claim isl. A stopper forbottles comprising two longitudinally-separable sections of like form,designed to be placed together and to form a complete closure for thebottle; and a device independent of said sections, comprising means forholdingthe same together and means for securing them within thebottleneck, substantially as described.

2. A stopper for bottles comprising abody portion secured within theneck of the bottle; a series of connected cylindrical pockets therein,the pockets being formed with polygonal recesses throughout a portion oftheir length, the polygonal portion being of greater cross-area than thecylindrical portion and valves in said pockets.

3. A stopper for bottles comprising abody portion secured Within thebottle-neck; a series of connected pockets therein, said pockets beingcylindrical in cross-section at their ends and polygonal intermediatesaid ends; said polygonal portions being of greater crossarea than thecylindrical portions and valves placed in said pockets.

4. A stopper for bottles comprising a body portion secured within thebottle-neck; a series of connected pockets therein, said pockets beingcylindrical in cross-section at their ends and provided with roundedvalve-seats, the central portion of the pockets being of a diameterlarger than the end portions; and valves placed in said pockets.

5. A stopper for bottles comprising abody portion secured within thebottle-neck; a series of connected pockets formed therein, the altenating pockets being provided with studs or projections across one end; andvalves seated in said pockets, operating substantially as described.

6. A stopper for bottles comprising abody portion formed of two separatesections secured within the bottleneck; a pocket formed therein providedwith a curved seat at one end and with studs or projections extendinginto the pocket from the sections near the opposite end, and with apolygonal portion intermediate said curved seat and studs orprojections; and a valve placed in said pocket, substantially asdescribed.

7. A stopper for bottles comprising a series of longitndinally-separablesections; a recess formed in the outer face of said sections; and asplit spring-collar designed to iitwithin said recess and secure saidparts together.

8. A stopper for bottles comprising a series ot longitudinally-separablesections; a recess formed in the outer face of said sections; and asplit spring-collar designed to fit within said recess, said collarbeing provided with a spring-finger designed to engage with a recessformed in the bottle-neck.

. separable sections provided with a recess in their outer face; aspring designed to encircle said parts and iit within the recess; alinger formed integral with the body of the spring; and a recess formedin the interior face of the bottle-neck designed to receive said finger.

l0. The combination with a bottle provided with a narrow groove orchannel formed on the inner side of its neck, of a stopper formed with aseries of longitudinally-separable sections provided with an annularrecess upon their outer face; a spring-collar M designed to encirclesaid parts and lit within the recess; a finger N formed integral withthe body of the spring and designed to enter the groove in the neck ofthe bottle when the parts are in position, whereby the separablesections are locked together andthe stopper as a whole locked within thebottleneck against longitudinal movement therein.

In witness whereof I hereunto set my hand in the presence of twowitnesses.
